    22. Drag-and-drop

    This chapter covers

    • The drag-and-drop classes

    • Drag-and-drop operations

    • The shadow builder

    • Listening for drag-and-drop events


    Starting with Android 3.0 (API 11), developers can add drag-and-drop capabilities to applications. Drag-and-drop support is one of the neat features added in Android 3.0, a natural addition to touch-based user interfaces and tablets. Android 3.0 provides a complete framework for drag-and-drop that consists of multiple classes, events, and operations. Related to drag-and-drop are copy-and-paste operations. Although copy and paste has been around since API 1, a much richer clipboard API has been introduced in API 11.
